EXHAUST-CONDENSER FOR STEAM-EXHAUST PIPES.

Application filed March 31, A1908. Serial No. 424,319.

To all whom t may concern.'

Be it known that LJosEPH M. SEARLE,

of `Pittsburgh, Allegheny tcounty, Pennsyl- Vania, have invented a new and useful Ex-A haust-Condenser for Steam-Exhaust Pipes, of which the following is a full, clear, and

exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a section of my condenser;

Fig. 2 is a horizontal section on lines 'IIR-II' of Fig. 1; Fig. 3 is a vertical section on the line III-III of Fig. 1 with theV interior member omitted; and Fig. 4 is a horizontal section of a modification of'my invention.

My invention relates to exhaust condens-E ers and has for its object to provide a condenser of efficient, simple and cheap construction, which may be used at or near the foot of the exhaust pipe instead of at theV top, as is the common practice, and is adapt-Q ed to return the water precipitated by the condensation of the steam with substantiallyI no loss to the boiler. V

A further object attained is the prevention of the Yescape of the steam from the head of the exhaust pipe and ofthe consequentV uncontrolled precipitation of the moisture present inthe steam, which often results in damage to adjacent properties.

Referring to the drawings, th'esteam in-V take pipe 2 leadingfrom the engine or heater (not shown), has a flaring mouth 3 secured by bolts 4 to the condenser-5, whichv is positioned at the foot of the exhaust pipe 7 and fastened thereto by bolts 8. rlhe walls of the condenser 5 are formed by-a metal U-shaped shell 9 which is positioned on the supporting member 10, located in the drip pan 11. In the opening 12 of the condenser 5 over which the flaring mouth 3 isbolted is a plate or diaphragm 13, having two series of oblique parallel ribs 14 the two series meeting at the center from which they are inclined in opposite directions with cor-.

responding grooves 15 between them. The diaphragm 13 is secured at its top and bottom to the shell 9 and leaves the opening 12 unobstructed at the sides 16 and 17 thereof.

yLocated centrally in said condenser and below the exhaust pipe 7 and leading thereinto is a cylindrical member 18, positioned upon the supporting member 10, and with the opening therein corresponding to the opening 19 of the member; l0. Said cylindrical member 18 has a plurality of series the vapertures of one series staggered or otherwise with relation to the apertures of eachvadjacent series.

In operation, the steam` from theintale pipe'2 impinges directly against the diaphragm 13, changing the course yof the steam and separating the oil and water therefrom before it strikes the cylindrical member 18. The oil and waterbeing precipitated, pass into the shell of the condenser through the opening 21, while the steafmpasses into the Vcondenser 5 through openings 16 and 17 at the sides of the diaphragm 13 where a partial condensation of the steam takes place by contact with the cylindrical member 18.

The steam from this chamber passes through the openings 20 into the cylindrical member 18 and passes upwardly into the exhaust pipe 7. The water and oil from this chamber will pass to the drip pan 11 through openings 22 and 19. `The upward movement of the steamwithin the cylindrical membery will vcause a suction at the bottom'thereof 4and air will be drawn into said member through the opening 19. This action of the steam is similar to the well-known vacuum producing action of a steam jet. This constant inrush of relatively cold air into'the member 17 not only coolsk the walls of said member and increasesV its condensing` action, but this air is directly commingled with the steam entering said member. In this manner kthere is an lefficient condensing action both exteriorly and interiorly of the said member. The condensation within the member 18 tending to produce a vacuum also increases the flow of both air and steam therein. The water of condensation in the pipe7 and cylindrical member 18 will also iow c into the drip'panll, from which it can be of vertically inclinedy apertures 20,' withsoy said pipe extending a suitable'distance above the condenser and communicating with said condenser at its lower end Vfor admitting steam from the condenser to the pipe, said condenser having an inlet opening for the steam, the condenseralso .having an open-V ing to the atmosphere vat its lower end forV admitting air at atmospheric temperature to the co-ndenser and pipe to reduce the tem-y `perature of the steam andrau'se condensa`l tion of the steam before it reaches the top] of the pipe; substantially as described. Y

2. A vertically disposed steam exhaust' pipe having a discharge to the atmosphere at its upper end, a condensery connectedto said pipe at its lower end, said condenserr having inner and outer chambers, there be-l ing an inlet to the condenser for the steam, the pipe extending a suitable distance above the condenser, thecondenser alsohaving an opening to the atmosphere at its lower end for the admission of air at atmospheric temperature, there being a plurality of upwardly extending openings in the inner wall of the condenser to permit the steam to pass from the outer chamber to the inner chamber, which openings act as injectors forv drawing the air throughV the bottom of the condenser into contact with the steam for condensing the same; substantially as de'- scrbed. Y

3.-A vertically disposed steam exhaust, pipehaving a condenser connected to its` lower end, said condenser consisting or" al chamber. connected with the exhaust intake pipe, a cylindrical member in said chamber opening into the exhaust pipe and having a plurality ofupwardly extending openings.; vfor admitting steam from the chamber to; the cylindrical member, said cyiindrical' member being open to the atmosphere at its lower end to admit air at atmospheric temperature thereto'by the inject-or action of the upwardly extending openings, the commingling of the air with the steam within the cylindrical -member and exhaust pipe: 1

causing the same to 'condense before it@` reaches the top of the pipe, and a receptacleg opiesof this patent may be obtained for atgthe lower end of said cylindrical member for the water of condensation from the condenser, substantially as described.

thereto bythe injector action ofl the upwardly extending openings, the commingling of the vair withV the steam within the cylindrical member andv exhaust pipe causing the same to condense before it reaches the top of.

the pipe,- a separating diaphragm within said chamber, and a receptacle at the lower end of said cylindrical member for the 'water of condensation from the condenser;

substantially as described. 1

5. The combination with a vertically dis- Vposed steam exhaust pipe of a condenser connected to the lower end of said exhaust pipe, said condenser having a chamber provided with an inlet connection for exhaust steam, a cylindrical member or tube extending vertically through the chamber and communicating with the exhaust pipe at its upper end andV open to the atmosphere at its lower end, there being a plurality of rows of upwardly extending openings through said cylindrical member for admitting steam from the chamber to the cylindrical member, anda drip pan at .the lower end of said end to admit at atmospheric temperature cylindrical member for receiving the water of condensation from the condenser and'exhaust pipe; Vsubstantially 'as described.
